1. The problem statement, all variables and given/known data Two forces act on an object at an angle of 50°. One force is 150 N. The resultant force is 200 N. Find the second force and the angle that it makes with the resultant. 2. Relevant equations Ux=|U|cos(theta) Uy=|U|sin(theta) 3. The attempt at a solution Basically I began by trying to find the components of the 150 N force by using the formulas mentioned above, which left me with U = [150, 0]. I then tried adding the two forces together, i.e. R = [150 + vx, 0 + vy] and then tried to find the magnitude of the resultant, which I knew was equal to 200. I squared both sides leaving me with (150 + vx)^2 + (0 + vy)^2 = 40000, however I did not know where to go from here. Any help is appreciated, thanks alot.
